AOC (Active Optical Cables) and DAC (Direct Attach Cables are both preassembled modules with cable, they are used in the data center and enterprise networks, AOCs and DACs are plug and play, allowing the existing cabling resources to upgrade without installing new fiber optic normally the DACs and AOCs are with standard cable lengths and […]
Based on MSA (Multi-source agreement), The are many forms of fiber optic transceivers, each pluggable optical transceivers with different transmission distance options, it including form factors, such as the SFP, SFP+, XENPAK, QSFP, XFP, CFP etc.; GBIC – First generation transceivers with SC fiber interface, commonly used with Gigabiy Ethernet and fibre channel, also available […]
The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It […]
Before you install the MPO connectors in the data cnter, it is essential that all the fiber end-faces and the ferrule are really clean. especially when you thinking about lining up 12, 16, 24 or 32 pieces of 9um fibers in one or two rows, it requires tremendous precision. Any dirts in the mix on […]
The QSFP form factor is today’s industry workhorse for delivering 40 and 100GbE. The “Q” is for “quad” — a nod to the four-channel electrical interface, with each lane running at 25 Gbps for 100GbE. QSFP-DD adapts the same basic concept as its predecessor, but doubles the electrical contact density, via eight differential pairs capable […]
SFP-DD is short for SFP Double Densty, it is a new module and cage/connector system similar to current SFP module, but with an additional row of contacts providing for a two lane electrical interface. It is being developed by the SFP-DD MSA as a key part of the industry’s effort to enable high-speed solutions. The […]
OSFP is short for Octal Small Form Factor Pluggable. it is being designed to use eight electrical lanes and each lane for 50GBE to deliver 400GbE. compared with QSFP transceiver, It is slightly wider and deeper, but it still supports 36 OSFP ports per 1U front panel, enabling 14.4 Tbps per 1U. OSFP is a […]
The C form-factor pluggable (CFP) is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum), since the standard was primarily developed for 100 Gigabit Ethernet systems. CFP8 use of a 16x25G electrical interface […]
How many form factors for 100G Optical Transceivers? QSFP28: Taking the technology and squeezing down to the familiar QSFP form factor CFP: The first 100G transceiver form factor, CFP’s are larger modules, and were based originally on 10 lanes of 10G CFP2: The successor to the original CFP module, this boasts a higher port density […]
What Is DDM (Digital Diagnostic Monitoring)? DDM is short for Digital Diagnostic Monitoring, according to the industry standard MSA (Multi-Source Agreement) SFF-8472 and is also known as DOM (Digital Optical Monitoring). When choosing the fiber optic transceivers for your equipment, you can choose transceiver modules with or without DDM/DOM function. Most of fiber optic transceivers […]
